UIExample fails

[hanbaoan123]

Issue Description

When I visit 'http://localhost:9000/train/overview' after running UIExample, it returned 'Internal Server Error' and the following error. Is there something wrong?

How are you running this example? Have you changed anything about the dependencies?

The error message tells you that there is no method readLines on IOUtils, but that would only happen if it picked up an incompatible version of apache commons.

I just add the following into my pom.xml and haven't changed anything.
